Thomas Tuchel has confirmed the Chelsea team news to face Manchester City in the FA Cup semi-finals on Saturday evening at Wembley.
Chelsea head to Wembley looking to reach the FA Cup final for the second successive season, but will be keen to go one step further after falling to defeat against Arsenal last August.
They will come into the clash against Pep Guardiola's side with confidence after securing their place in the Champions League semi-finals after seeing off Porto in midweek.
And Tuchel confirmed the team news on Friday in his pre-match press conference that Christensen and Kovacic would both miss the match through injury.
However, the Blues boss did confirm that N'Golo Kante would be fit to face Man City and is expected to start at Wembley.
"Yes to both questions [Kante playing another 90 minutes and Billy GIlmour being a part of the squad]," revealed Tuchel.
"We have the green light for N’Golo to play another game because we had three days between our last game and this one to work with him. He is ready.
"Mateo is unfortunately still out. Already he is feeling better but he still out and cannot be in the squad for tomorrow. It is the same with Andreas Christensen, he is also out."
Sergio Aguero is out for Man City after Pep Guardiola confirmed he isn't fit enough for the semi-final clash.
